I think I may be having an issue receiving the emails from your sign up list, is there a way it can be tested?

Last night while checking my email on my phone, I saw something unread that mentioned Alliance badges, tried to open it, but then the page refreshed and it was just gone. I've dug through my email and I can't seem to find it anywhere, not even trash. I got the feeling from checking up on your site that email went out sooner than yesterday? I'm not really sure
